Hello everyone,
Today yet another test with infrared filters.
Work has been very busy lately and I wasn’t able to post at all nor develop on my projects much.
Also why this post will be very brief. My apologies for that.
I will make more detailed ones in the future!
Below two infrared test with and old classic from Leica:the Summicron C 40mm/f2.0, mounted on the new digital Leica CL. Looking at these pictures you need to factor a 1.5 focal length change.
The first gallery is taken using the Kolari Vision IR Chrome filter.
From left, it starts with f2.0, to end at f16.
